The figure below is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, an outer conductor, and another rubber layer. In a particular application, the current in the inner conductor is I = 1.10 A out of the page and the current in the outer conductor is 12 = 2.86 A into the page. Assuming the distance d = 1.00 mm, answer the following. * (a) Determine the magnitude and direction of the magnetic field at point a. magnitude direction ---Select--- (b) Determine the magnitude and direction of the magnetic field at point b. magnitude direction ---Select---
